G protein coupled receptor 84(GPR84) is medium-chain fatty acid-sensing receptor(C9~C14). It plays an important role in metabolism of fatty acid and immune response, and it's also deeply involved in inflammatory immune diseases such as multiple sclerosis and endotoxemia. It may provide an effective method to treat these diseases by finding GPR84 ligands. It's important to construct a cell line stably expressing human GPR84 for screening its ligands and researching diseases. In this research, we transfected ...
